Description

A kind of test data automatic derivatization method and apparatus of data base-oriented
Technical field
The present invention relates to computer software testing, and relate in particular to a kind of test data automatic derivatization method and apparatus of data base-oriented.
Background technology
In software development process, system testing is an indispensable part in SDLC normally, and the quality direct relation of test the quality of system.In real test process, the division of test-types is varied, and white-box testing, Black-box Testing, functional test, performance test etc. are arranged.Therefore, in test process, also different to the demand of test data.
At present, the main generation means of lot of domestic and foreign software test data are manual modes.The preparation of test data is all relied in artificial writing.But manual type only can be tackled simple functional test; When the data volume of the test data that will write based on test cases very large, perhaps require test data to produce various variations, when perhaps test data must satisfy some certain logic relation and adapts to various test scenes and test cases, generate test data by manual type, usually can't produce at short notice a large amount of test datas, the establishment of each data all needs manual intervention, and the tester has also been proposed highly difficult requirement, so test will take time and effort very much and testing efficiency is lower.In this case, the craft of test data prepares to become the bottleneck in software test procedure.
The automatic derivatization of test data can improve this ink-bottle effect in software test procedure greatly.Application number is that 02139613.2 the disclosed automatic generation of test data of Chinese patent application has proposed a kind of automatic generation method towards Program path, this method by input interface, lexical analyzer, syntax analyzer, constraint constructor, constraint solver, path satisfy detector, output interface module realizes that test data generates automatically, the method comprises following 4 steps:
(1) user is from initial value and increment and other parameter value of input interface designated program path W, each input variable, as all predicate functions on W whether be the linear function of input variable, when certain predicate function on W is the nonlinear function of input variable iterative the number of times upper limit and when comprising read statement in having black box and black box on W, according to the number of the input variable in the black box of the interface specification defined of black box and data type of each input variable etc.;
(2) after lexical analyzer carries out lexical analysis to W, syntax analyzer carries out grammatical analysis according to the result of lexical analysis to W, W is converted to constraint constructor and path satisfies scrutiny program, the constraint constructor produces the constraint constructor through compiling, and the path is satisfied scrutiny program and produced the path through compiling and satisfy detector;
(3) the constraint constructor is according to the statement on the increment execution W of present procedure input and each input variable, do not analyze the data dependence relation between the statement on W, the linear arithmetic of upper each predicate function of structure W represents, then sets up the linear constraint system of input variable;
(4) the constraint solver method that adopts linear programming, linear integer programming, linear mixed integer programing and least square solution to combine is found the solution this linear constraint system: if the user specifies predicate function on W to be the linear function of input variable, adopt linear programming, linear integer programming, linear mixed integer programing method to find the solution; If the user specifies the nonlinear function that contains input variable in predicate function on W, first adopt linear programming, linear integer programming, linear mixed integer programing method to find the solution, if can't find solution, this linear constraint system is converted to linear equation system, ask its least square solution; Finding the solution the new program input of rear acquisition is test data; Satisfy detector inspection by the path at last, if the input of this program can make W by through finishing, if this program input can not make W be determined whether to continue iterative by the linear function and the iterations upper limit that through all predicate functions upper according to W are whether input variable; Solving result is exported by output interface.
The algorithm logic of said method is too complicated, and the method lacks certain simple and easy maneuverability in practice.
Application number is a kind of method that 200910147768.0 the disclosed automatic generation of test data of Chinese patent application has proposed embedded software test exploitation, and the method comprises following 8 steps:
(1) load testing scheme, described testing scheme is that according to characteristics and the test request of tested software, the input of clear and definite test development work forms according to the analysis to tested embedded software document;
(2) test environment configuration is configured according to the general parameter of testing scheme to embedded software automatic test environment, so that the test environment that generates configures adaptive automatic test platform better;
(3) crosslinked environmental modeling is namely completed the structure of cross-linking apparatus realistic model, generates the information of described cross-linking apparatus realistic model;
(4) test script is developed, and namely calls the information of described cross-linking apparatus realistic model, and the tested tissue process is selected the test script language, generates test script;
(5) test panel exploitation, use test panel plug-in unit allows the user to set up the test display panel by pulling in visual virtual instrument mode;
(6) test assignment management, use test task management plug-in unit is organized each test required realistic model file, test script file, the information such as test panel file neatly in the mode of test cell;
(7) generate the test configurations information of XML-based form and the description of test data;
(8) transfer to automatic test platform and carry out, test configurations information and the test data of the XML form that has soon generated are loaded into the fc-specific test FC platform, can drive test process, complete the automatic test of embedded software.
Said method for be embedded system, can't be applied on the application software system based on relevant database of enterprise-level, so there is certain limitation in its application.
Therefore, the test data automatic derivatization method and apparatus that needs a kind of data base-oriented.
